South Syrian rebels said on Friday they had agreed with Russia to cease fire and start handing over heavy weapons.
A commander in the regional alliance supporting Head of Syrian Bashar al-Assad had earlier said regime forces were advancing through rebel territory along Syria's frontier with Jordan and would soon reach the countries' main border crossing, according to Reuters.
The rebels said the deal was brokered by Russia and would allow both "fighters and civilians" in opposition areas to settle their status with the regime under Moscow's protection.
Rebels who did not wish to come back under Assad's rule would leave for the insurgent stronghold in northwest Syria, they said.
The commander in the pro-Assad alliance told Reuters "the army and its allies had seized a string of villages and reached the border."
"Within a short period of time, they will reach the (Nassib) crossing," the non-Syrian commander said, speaking on condition of anonymity.
Hundreds of troops in a large military convoy with Russian and Syrian flags were seen heading to Nassib border crossing.
